METHOD OF BLEACHING AND APPARATUS THEREFOR.

To all 'whom it may concern v Be `it-known that I, CHARLES TAYLOR, a subject of the King of Great Britain, residing at 123 Station road, Kearsley, near Man chester, in the county of Lancaster, England, have invented certain useful `Improvements in Methods of Bleachin and Apparatus Therefor,as set forth in t e annexed specification. f

`This invention relates to the bleaching `of fabrics inpieceform. l

Hithertoit has been customary when employing round keirs for the bleaching process, to fill the boiling keir by hand, and after `the boil was complete, to remove the cloth fromlthe boiling keir into" the chemical and 1acid` tankagain by hand which method necessitatedthe employment of a number of skilled piling boys, a considerable loss of time` inlling the keirs, faulty bleaching, and repeated handling by the operatives of the whole of the pieces attached together.

The object of my invention is to render the process of bleaching automatic from beginning to end, whereby the-`amount of skilled labor and `time employed is greatly reduced, chemicals are economically utilized, danger to life is reduced, and a comparatively perfect bleach is obtained.

According to my invention, my improved method consists in leading the pieces in rope form automatically from one keir direct into the next keir, and direct from the last keir through the white mangle into the folding device.

My improved plant for carrying out said method includes a round iron keir, a round wood keir, an expander, a white mangle and a folding device arranged in a row, in combination with an automatic piler arranged over each keir androtated means for passing the fabric in rope form fromone keir to the piler on the next keir used in perform in the bleaching operation.

I attain the hereinbefore recited objects "b the hereinafter described method and the p ant illustrated diagrammatically in the drawing which I have caused tobe appended hereunto.

Referring to the drawing which shows a plant for handling 10 tons per 12 hours, two iron keirs 1, 2 are arranged in alinement with a singeing machine or padding machine (not shown), a set of squeezing and drawing Patented N0v.15,1921.

rollers 3 being interposed between the first keir 1 and the said machine. Two wood keirs 4, 5 are also provided in alinement with the iron keirs 1, 2 and-av mangle 6 is interposed between the second iron keir 2 and the `Wood keil- 4. l Each of the keirs 1, 2, 4 and 5, which as shown may be of the bottle `neck type, has anv automatic piler 7 suspended above it from a beam`8, said pilers 7 being preferably constructed and arranged to operate as described in Patent No. 1,328,615, is-

suedon the 20th January, `1920, and a mechanically rotated guide drum 9 is mounted above each keir to pass the fabric direct from the"` squeezing and drawing rollers 3 into the upper end of the automatic piler 7 on one or other of the iron keirs 1, 2 and direct from 'either of the iron keirs 1, 2 into the automatic piler 7' of oneor the other of the wood keirs '4, 5." Situatedin alinement with the wood -keirs 4, 5I provide a white mangle 1() and two folding devices 11 and I mount on the beam 8, two expanders12, the arrangement Vbeing such that the fabric can be passed direct from eitherof the wood'keirs 4, 5

through one of the expanders 12 and from `then'cethrough the whitemangle 10 into one of the folding devices 11. In lieu of one white mangle for both cloth ropes, I may provide a separate white mangle for each of them.

The improved method of bleaching as performed on the improved plant illustrated consists in passing the end of two fabric ropes 13, 14 through the mangle 3 when it emerges from the singeing machine or padding machine, and in passing the rope 13 into the automatic piler 7 on the iron keir 2 and the rope 14 into the iron keir 1, whereupon the pilers 7 automatically fill the keirs 1 and 2. After the boil is complete, the accessible end of the rope 13 is lifted from the iron keir 2 and led through white mangle l0 to the folders 11 which ythen automatically empty the wood leirs 4L, and 5.

It will be appreciated that during the -whole duration of the bleaching process,

only the extreme end of each rope of fabric requires to be manually handledand that such handling is only necessary for short periods with long intervals between. When employing my improved piler, the liquor is pumped intoV the lreirs by the pumps 15 and by passing through the piler 7V with thevi'abric rope eifects theintroduction of the rope into the 'keirs The chemicals, after use in the wood keirs 4 and 5 are returned to tanks 16 and 17 -fromV whence they are again pumped back into wood keirs during the next piling operation. f

I claim: v

1. A methodof bleaching clothin rope form in keirs, vconsistingin passing two ropes of clothV simultaneously through a mangle; mechanically introducing into vand automatically piling inra boiling keir one of said ropes; mechanically introducing into and automatically piling in a second boiling keir, the other of said ropesvin a simultaneous manner; boiling said ropes of cloth; withdrawing said ropes and passing them simultaneously through a mangle; mechanically introducing into and automatically piling in a woody keir one of said ropes; simultaneously introducing mechanically into and automatically piling in another wood keirY kthe other of said ropes; treating said ropes in said wood keirs; simultaneously withdrawing and expanding said ropes; passing said ropes together through a white mangle; and then simultaneously folding both of said ropes of cloth.

2. An improved bleaching plant comprising a round iron keir, a round wood kcir, an expander, a white mangle and a fold ing device'arranged in a row, in combination with an automatic piler arranged over each keir and rotated means over each keir adapted to pass the fabric in rope form from one keir to the piler on the next keir used in performing the bleaching operation.

3. An improved bleaching plant comprising in combination, a set of squeezing rollers; two iron keirs in alinemen't with said set of squeezing rollers; two wood keirs in alinement with said iron keirs, a second set of squeezing rollers interposed between said iron keirs and wood keirs; two folding devices in alinement with said wood kcirs; a white mangle between said folding dcvices and said wood keirs; an automatic piler arranged over each of said keirs; a member supporting said pilers; rotated drums mounted on said member to guide cloth in rope form to said pilers; and expanders on said member to expand the cloth in rope form beiore it passes through the white mangle, for the hereinbefore specified purpose.
